Specification forming part of Letters Patent No. lld?, dated December24, 1872.

To all whom it may concern:

Be it known that I, CHARLES B. Woon, of Mansfield, in the county ofBristol and State of Massachusetts, have invented an Improved Oiler forMachinery, of which the following is a full, clear, and exactdescription, reference being had -to the accompanying drawing makingpart of this specification, in which- Figure l is a perspective view ofmy iinproved oiler, and Fig. 2 is a vertical section through the centerof the same.

My invention consists in the peculiar construction of the bottom of theoil-receptacle, which is made conical, and is provided with an openingfor the admission ot' air, which is automatically closed by a valve toprevent the escape ofthe oil when the oiler is set on its bottom, asecondary or lower bottom with an aperture for the admission of airbeing also provided to still further guard against the escape ofthe oil.

To enable others skilled in the art to understand anduse my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawing, A represents the oilreceptacle, the upper portion bof which is oi' conical form, and has screwed into it the lower'end ofthe discharge pipe or nozzle B,

which is provided with a small dischargeopening, c, at its upper end.Across the interior of the portion b is secured a small strip or brace,d, to which is attached a vertical rod or wire, c, which passes upthrough the nozzle B, and when the latter is screwed down tight thetapering extremity of the rod c projects through the opening c andentirely closes-it.

When, however, the nozzle is raised by parically oil a certain portionct' a machine; or a steady stream may be allowed to escape from theoriiice c by sufficiently unscrewing the pipe B. l

f is au elastic packing-ring, which is fitted over the upper end of theconical portion b of the oiler, and is forced down thereon by thecontact of the iiange at the lower end of the discharge-pipe. This ringprevents lealiage of the oil, and also steadies the dischargepipe whenpartially unscrewed. The bottom got the oil-chamber is made extremelyconical, its upper end rising into the conical portion b. At the apex ofthe bottom g is a small aperture, lz, for the admission of air to theoil-chamber, and this opening is closed to prevent the escape of theoil, when the can is in the position seen in the drawing, by a valve,t', to the lower end of the stem of which is attached a conical weight,7c, having grooves Z in its sides to admit the air to the opening 7Lwhen the oiler is tipped up to discharge the oil.

The valve 'i thus prevents the escape of the oil when the oilchamber isilled above the level of the top of the conical bottom g. Some or" theoil might, however, adhere to the stem of the valve 1i, when the oileris used, and run down onto the weight lo and drip therefrom. I thereforeemploy a secondary bottom, a, which is provided at its center with ashort conical tube, m, having an opening, 5, at its top for theadmission of the air. A chamber is thus formed beneath the bottom g forthe reception of any oil which may drip down from above, and, as theapex of the conical tube m is directly under the center of the weight7c, no oil can escape through the opening 5, as it will drop onto thesides of the tube m; and any oil which may collect in the lower chamberwill run back into the oilchamber through the grooves in the weight k,when the oiler is inverted or tipped up for use.

The oil-chamber may be filled through the opening left by removing thedischarge-pipe B,

or the oil may be introduced at the bottom oi the oiler through the pipem. The latter might be found convenient where the oiler is set in aninverted or inclined position for the 2. Thesecondary bottom a providedwith purpose of automatically oiling a cert-ain po1'V an aperture forthe admission of air, in comtion of a machine. binatiou with the bottomg and valve i, subl Olm-m8 stantially as and for the purpose set forth.'f

Witness my hand this 7th day of Septem- What I claim as my invention,and desire to Yber, A. D. 1872. secure by Letters Patent, is- CHARLES B.WOOD..
